Abstract

Abstract Intra-articular fractures of the distal tibia are complex with a high risk of complications before and after surgical treatment. Tibial pilon fractures are rare but present a serious challenge for orthopedic surgeons. There is still no universally accepted treatment protocol for pilon fracture. In traditional, the reduction of fractures has some drawbacks such as the risk of infection, low accuracy, and high radiation for surgeons. Particularly complex intra-articular fractures require a lot of force. To solve such problems, a detachable hybrid robotic system has been developed that combines a detachable parallel mechanism with a drive mode. This article describes the mechanism in detail, analyses the method of fracture reduction, presents the surgical manipulation, and verifies the reduction by experiments with bone models. The article presents the results of research to solve problems of pilon fracture management.
